Description
技术领域
本发明涉及细胞提取技术领域,具体为一种用于化妆品脐带间充质干细胞提取物的制备方法。
背景技术
间充质干细胞是来源于发育期早期中胚层和外胚成的一类多能干细胞。具有免疫调控、能够修复损伤或病变的组织器官、具备多向分化潜能等功能,因此具有广泛的应用前景。
干细胞抗衰老基于其两种基本功能,一是干细胞的增殖分化能力,可以分化成不同的体细胞以代替衰老死亡的机体细胞,二是干细胞的旁分泌功能,可以产生许多生物活性分子,间充质干细胞一个强大的功能就是分泌众多的营养性细胞因子。越来越多的研究表明,间充质干细胞旁分泌作用在其发挥治疗效果中起主要作用。
目前市面上添加到化妆品中的成分多为干细胞培养上清液,该上清液分泌因子含量低、均一性差、稳定性差,美容效果一般,且提取上清液的效率低下,因为提出了一种用于化妆品脐带间充质干细胞提取物的制备方法。
